3. Experimental procedure
Several welding trials are conducted with alloy steel tubes (T11)
of 47.6 mm outer diameter and 6.6–7 mm thickness using MD1
MIAB machine with different sets of input parameters. Horizontal
position is being considered for all the experimental trials. Material
specifications include the chemical composition and the tensile
requirements for MIAB as provided in Table 1.
MIAB being a relatively new welding process and due to inadequate
availability of literature, initially, trial and error method is
